j CAN-OPENER.

' Application filed February 25 To all whom z' may concern.' f A p 1 Beit known that 1, Louis JAKUBEG, a subject of the Emperor of Austria,(having declaredmy intention to become a citizen of the United States ofAmerica,) residing at Salem,-in the county of Marion and State ofOregon, have invented certain new and useful Improvements inGan-Openers, `of which the following is a specification.

f Thisinvention relates to certain new and useful improvements in canopeners.

The primary object of the invention is the provision of a device formaking circular cuts in sheet metall such as tin and so. a1?- rangedthat circles of different diameters mayl be cut by the device, the samebeing suitable in construction and easy and inex-l pensive tomanufacture.

A further object of the invention is the provision of a hand implementarranged for `cutting circular openings of different diameters in theends of tin cans for `gaining access to the interior of 'the can, thedevice possessing great strength and durability. I

In the drawings forming a part of this application and in which likereference characters refer to corresponding parts throughout the severalviews,

Figure 1 is a central longitudinal sectional view taken through thedevice with the handle broken away and the pivot member illustrated bydotted lines in its adjusted position. Y

Fig. 2 is a side elevational View thereof,

Figs. 3, 4, 5 and 6 are transverse sectional views of the same takenupon lines III-III, IV-IV, V-V and VI-VI, respectively of Fig. 1.

Fig. 7 is aperspective view of the free end portion of the shaft portionof the dev1ce,

Fig. 8 is a perspective view of the point member employed and Fig. 9 isan elevational view of a modified v form of Construction partiallybroken away.

My device being adapted for making cir-` cular cutsl in tin bodies, thesame broadly consists of a tubular shaft 10 fixedV to the end of anoperating handle 11'and provided with an adjustable centering point 12upon its free end with metal cutters 13 and 14 upon the opposite sidesof the shaft and one specifieauen of Letters Patent.

The shaft 10 is arranged with a screw 15 axially journaled therein withits inner end connected by means of a swivel 16 with the inner( end orhead 17 of the shaft, which head is attached tothe handle 11 by rivets18.

A longitudinalv side slot l9 isprovided in the shaft 10 at the sidethereof opposite the cutter or blade 13 andthepoint 12 ,has an attachingsleeve 2O through which the screw 15 is journaled, opposite projectinglugs 21 andv 22y being if carried by the sleevey 20 yfor seating withinthe adjacent end' of the sloty 19 and an oppositely arranged notch 23kprovided inthe end of the shaft 10.

A `locknut 24 is threaded upon the screw lputwardly ofthe sleeve 20 forlocking the partstogether` preventing the screw 15 from rotating Themovable cutter or blade 14 is vprovided with a collar 25 slidablyarranged within the shaft 10 and threaded upon the screw 15 forlongitudinal movement` during the turning of the screw by means of ahandle 26 carthe outer free end of the screw.

The cutter 14 is shaped substantially like an arrow head having a neck27 slidably arranged within the slot 19. During the operation of thedevice, the point 12 and cutter 1 3 may be employed for cutting a circleof a radius equal to the distance between the point 12 and the cutter13, the point 12 being punched'through the'work such as tin and a handle11 employed for revolving the shaft 10 around the point 12 as a centerwith thel cutter 13 cutting through the tin. Y f

When it is desired to cutY a circle having a kradius of a differentlength from that just described, the nut 24 is turned and movedoutwardly upon the screw 15, releasing the sleeve 20 and permitting thepoint 12 to be to that illustrated by dotted lines in Fig. lof thedrawing. The point 12 will then be in a position for cooperating withthe adjustable cutter 14 which cutter is adjusted for cutting 'a circleof the desired diameter by moving the screw 15 by means of its handle 26for feeding the cutter 14 longitudinally of the shaft 10. When thecutter 14 is properly positioned, the nut 24 is tightened upon thesleeve 2O during the operation of the device.

In the modified form of the invention shown in: Eig. 9, a shaft 10 isprovided fixed upon a'ha-ndle'- l1 the shaft. A'polntmember :12 iscarried by" a threaded' terminal4k portion 1'5"v ofl the shaft 10 theShaft' said; cutters While lockV nuts 24" arecarried byt-heterminal'port-ion.15y for locki'ngthe point member 12" in either oflits opposite sitions.- The 'operation of this forni of 51e device willbe apparent, the cutters being serviceable selectively With the pointmember 12jivhen positioned upon the side of'v thesha'ft 10? `v`adjacentsuch cutter.
